How to adjust the headlights on an Audi A4?

I need to adjust the headlights on my Audi A4 as they seem to be shining too high. How can I do this without going to the mechanic?

Start by locating the adjustment screws on your headlights, one for the vertical and one for the horizontal adjustment. Use a Phillips head screwdriver to make the necessary adjustments, typically clockwise for up and down and counterclockwise for left and right. Be sure to test the headlights after each adjustment to ensure they are properly aligned.
